I need help in changing the permission on a couple different drives. I have two USB keys that I use to move files around. I can write to them just fine, but I can't un-mount them. So far I have just been pulling them out and pluging them in and letting Mandrake auot-mount them. But every now and than files are getting screwed up or I can't get it to auto mount again after I pull it out. I think actually un-mounting it before I pull it out would help. I tried to change the permission on them from Root but it didn't seem to work. What do I need to change in order to let me unmount these things.
